4. Beneath the Manicured Lawn

The doors of the Ashworth house unlocked at 6:03 a.m. with a sound like a long exhalation—a soft pneumatic sigh that rippled through the house and left twenty survivors blinking in the gray November dawn. Erik Sandberg had been awake for hours, his back pressed against the dining room wall, Liv’s head resting on his shoulder. No one had spoken since the verdict. No one had dared.

He watched his neighbors rise like flood survivors, stiff-limbed and hollow-eyed, stepping over the bodies as if they were furniture. Someone vomited into the cornucopia. Someone else began to laugh, a high thin sound that went on too long. Erik pulled Liv to her feet and led her through the front door into the cold air that smelled of wet leaves and woodsmoke and the distant hum of lawnmowers.

The street was waking. Sprinklers ticked on. A dog barked. Somewhere a garage door rumbled open, and Erik thought: They don’t know. The whole neighborhood, still wrapped in the routine of an ordinary Saturday morning, had no idea that four people were dead and the survivors carried the votes in their phones like stones sewn into their pockets.

The first patrol car arrived at 6:17, followed by two more, then an ambulance that had nowhere to go. Officers in fresh-pressed uniforms fanned across the lawn, their hands resting on their holsters, their faces cycling through confusion and horror as they entered the house. Erik sat on the curb with Liv and watched the forensic vans roll in, white and silent as hearses.

Detective Inspector Marta Voss arrived at 6:47. Erik recognized her type immediately—the weary competence, the eyes that had seen everything and expected worse. She was fifty-three, broad-shouldered, with gray hair pulled back in a knot that had been tight when she left home but was already coming loose. She stood on the Ashworth porch for a long moment, surveying the street with an expression that reminded Erik of his old site foreman, a man who could look at a foundation and see the cracks before they formed.

“Mr. Sandberg.”

He looked up. She had crossed the lawn without him noticing.

“I’m Detective Voss. I understand you and your wife were inside all night.”

“Yes.”

“I’ll need to take your statement. Both of you. But first—” She paused, and her gaze dropped to his cane, then to the surgical scars visible above his collar. “First, tell me what happened in your own words. Not the official version. The real one.”

Erik told her. He told her about the moving truck and the NeighborWatch notifications, about the photograph taken through the kitchen window, about the dead bird and the note that said PARTICIPATE. OR ELSE. He told her about the banquet, the toast, the lights going out, the carving fork in Gerald Ashworth’s hand. He told her about the voice, the polls, the votes, the basement door opening and closing. He told her about Oliver Thorne, standing in the corner with his sparkling water and his wire-rimmed glasses, opening the door for the masked figure. He told her about Eleanor Davison, who had exposed Oliver and saved his life.

Marta listened without interruption. When he finished, she was quiet for a long moment.

“The basement,” she said. “Tell me about the figure in the basement.”

“There was a mask. White. No features. The build changed.” He frowned, trying to remember through the haze of adrenaline and exhaustion. “The first time, when it killed Marcus Davison, it was larger. Broader. The second time, for Celia Ashworth, it was smaller. Faster. I thought it was just the suit, but—” He stopped.

“But what?”

“The third time. Oliver. The figure that killed Oliver moved differently. It knew him. There was a pause before the strike, just a fraction of a second. Like recognition.”

Marta’s expression did not change, but something behind her eyes sharpened. “Thank you, Mr. Sandberg. Wait here. I’ll have an officer take your formal statement.”

She walked back toward the Ashworth house, and Erik watched her go. Liv stirred beside him, her hand finding his.

“She believes us,” Liv said.

“She believes something.”

Marta spent the next two hours inside the Ashworth house. She walked the perimeter of the dining room four times, memorizing the position of every body, every piece of overturned furniture, every bloodstain on the Persian rug. The forensic team moved around her like water around a stone, photographing and bagging and measuring, and she absorbed their reports in fragments: the carving fork was from the Ashworths’ own kitchen set; the basement door had been rigged with an electromagnetic lock controlled by a signal from Oliver Thorne’s phone; the mask was a commercially available costume piece, ordered online six months ago.

“The servers,” she said to the lead tech, a young woman named Reyes with ink-stained fingers and a face that had not yet learned to hide its horror. “What have you found?”

“It’s a custom setup. High-end. Someone spent a lot of money on this.” Reyes gestured at the racks of humming machines. “There’s enough processing power here to run a small corporation. The NeighborWatch app was just the surface layer. Underneath, there’s a complex machine-learning algorithm designed to analyze user behavior, identify patterns, and generate content.”

“Content?”

“Posts. Polls. The Verdict account wasn’t operated by Oliver Thorne alone. It was partially automated. The algorithm scraped public records, social media, even dark web data, and compiled dossiers on every resident. Then it generated posts in the style of the most active users. It learned what the community wanted to see and gave it to them.”

Marta stared at the blinking lights. “It wrote the verdicts.”

“It suggested them. Someone still had to execute. But the line between suggestion and command—” Reyes hesitated. “It’s blurrier than I’d like.”

“Show me the logs.”

They moved to a monitor, and Reyes pulled up a cascade of text. IP addresses. Timestamps. Account identifiers. Marta traced the lines with her finger, watching the network take shape. Each house on Primrose Lane had at least one device connected to the app. Most had more. The traffic patterns showed a cluster of activity around each execution—a surge of data as the poll opened, a spike as votes were cast, and then a single command signal sent to the electromagnetic lock on the basement door.

“The command signal,” Marta said. “Where did it originate?”

“That’s the strange part. It didn’t come from Oliver’s phone. It came from a different device every time.” Reyes highlighted the data. “First execution: signal originated from 47 Primrose Lane. Second execution: 51 Primrose Lane. Third execution—” She stopped.

“Third execution?”

“Third execution, the signal originated from 38 Primrose Lane. But there’s a problem. 38 Primrose is the Ashworth house. And by the time the third signal was sent, both Gerald and Celia Ashworth were already dead or incapacitated.”

Marta felt the cold prickle at the back of her neck. “Someone else was in the house.”

“Or someone else had access to the Ashworth network. The signal was routed through their Wi-Fi. Anyone with the password could have sent it.”

Marta stepped back from the monitor. The basement seemed to close in around her, the hum of the servers pressing against her eardrums. Four bodies. Four executions. And three different people who had opened the basement door.

“Where are the survivors now?” she asked.

“Community center. We’ve got them separated, but they’re not under arrest. We can’t hold them without cause.”

“Oh, we have cause.” Marta pulled out the thumb drive Eleanor Davison had given her. “We have all the cause in the world.”

She spent the afternoon at the station, cross-referencing the server logs with the statements the survivors had given. The picture that emerged was both simpler and more terrible than she had expected.

The NeighborWatch app had been installed on every phone on Primrose Lane. Every resident had an account. Every resident had posted. Every resident had voted. But not every resident had known what their votes would trigger. The app had been designed, in its final iteration, to blur the line between virtual and physical. The polls were real. The verdicts were real. But the connection between the vote and the execution was hidden from most users. Only a handful knew what the basement door meant. Only a handful had the command code.

She identified three devices that had sent the execution signal. The first belonged to Marcus Davison’s phone—which meant someone had used it after his death. The second belonged to Elara Ashworth’s tablet, left on the kitchen counter where anyone could access it. The third belonged to a device she could not identify, a burner phone that had connected to the Ashworth Wi-Fi for exactly thirty-seven seconds and then gone dark.

“Three people,” she said to Reyes. “At least three people in that room knew what the votes would do and chose to open the door anyway.”

“Accomplices.”

“Worse. Participants. They weren’t following Oliver’s orders. Oliver was following theirs. He was the administrator, but someone else was giving the commands.” She leaned back in her chair. “Someone in that room wanted those people dead and used the app to make it look like a collective decision. The algorithm generated the posts. The community cast the votes. But the hand that opened the door—that was human.”

That evening, she went to the community center. The survivors had been given blankets and hot meals and the stunned solicitude reserved for victims of mass tragedy. They sat in small clusters, speaking in low voices, and Marta watched them through the window for a long moment before entering.

She found Eleanor Davison in the corner, still wrapped in her blanket, still clutching her phone.

“Mrs. Davison.”

Eleanor looked up. Her eyes were red-rimmed but dry. “You’ve been through the logs.”

“I have. You were right. There were three people opening the door. Not one.”

“Did you find them?”

“Not yet. The signals were routed through other people’s devices. Someone used your husband’s phone after he died. Someone used Elara Ashworth’s tablet.” Marta sat down across from her. “Mrs. Davison, I need you to think very carefully. During the banquet, did you see anyone near the Ashworth kitchen? Anyone who shouldn’t have been there?”

Eleanor closed her eyes. “It was chaos. After the lights went out, people were moving everywhere. I saw—” She stopped. “I saw Erik Sandberg’s wife. Liv. She was in the kitchen.”

“When?”

“After the second execution. After Celia. I went to the kitchen to find something to stop the bleeding, and she was there. Standing by the counter. She had a phone in her hand, but it wasn’t hers. It was smaller. A different color.”

Marta felt her pulse quicken. “Did she say anything?”

“She said she was looking for a first aid kit. But there was no first aid kit in the kitchen. I checked later. It was in the bathroom.”

Marta sat very still. Erik Sandberg had been the next target. The poll had been frozen mid-tally, the votes at sixteen. If Eleanor had not exposed Oliver, Erik would have been sent into the basement. And Liv—Liv had been in the kitchen, holding a phone that was not her own.

“Thank you, Mrs. Davison. You’ve been very helpful.”

She left the community center and walked back to 42 Primrose Lane. The house was dark, the curtains drawn. She knocked on the door, and after a long moment, Liv Sandberg opened it.

“Detective Voss.”

“Mrs. Sandberg. May I come in?”

Liv stepped aside. The house was still half-unpacked, boxes stacked against the walls, the air heavy with the smell of cardboard and uncertainty. Erik was sitting in the living room, his cane propped beside him, his face drawn with exhaustion.

“I have a few more questions,” Marta said. “About the banquet. About what happened in the kitchen.”

Liv’s expression did not change. “I told you everything I remember.”

“Did you? You told me about the dead bird. The note. The photograph. But you didn’t tell me about the burner phone you were holding in the Ashworth kitchen after Celia’s death.”

The silence in the room was absolute. Erik looked at his wife. Liv looked at Marta.

“I found it,” Liv said quietly. “On the counter. It was ringing. I picked it up.”

“Who was on the other end?”

Liv’s hands were shaking. “No one. It was just a text. A single line. ‘The next vote is for him. Open the door, or I will.’ I didn’t know what it meant. I didn’t open any door. I put the phone down and walked away.”

Marta studied her face. “Why didn’t you tell me this earlier?”

“Because I was afraid. Because someone in that room was sending the signals, and I didn’t know who, and I still don’t know who.” Liv’s voice cracked. “I was trying to protect my husband.”

Marta reached into her pocket and pulled out the burner phone she had found on the Sandberg porch that morning. “Is this the phone you saw?”

Liv stared at it. “No. That one’s different.”

Marta set the phone on the coffee table. It was small and black, the kind of phone you could buy at any convenience store, and it was still warm. “This was left on your doorstep this morning. Addressed to you. Did you open it?”

Erik leaned forward. “We didn’t order anything.”

“I know.” Marta picked up the phone and turned it on. The screen lit up with a single notification from the NeighborWatch app. A new post, pinned to the top of the feed:

*Welcome back, Erik Sandberg. The trial is not over. The community is not satisfied. The algorithm has identified a new threat. Your vote will be required soon.*

Beneath the message was a photograph. It was taken inside the Sandberg house, through the same gap in the curtains that had captured Erik’s surgical scars four days earlier. The photograph showed Erik and Liv sitting on the couch, their heads bent together, their faces illuminated by the glow of a phone screen.

Marta looked at the timestamp. The photograph had been taken thirty minutes ago.

“Someone is still watching,” she said. “Someone is still running the algorithm. And whoever it is, they want you to know that the trial isn’t finished.”

Erik’s face had gone gray. “We’re not safe here.”

“No,” Marta said. “You’re not. None of you are.” She stood up and walked to the window. The street outside was dark, the perfect lawns silvered by the moon. The cameras were still watching, their red eyes blinking in the autumn night. “I’m placing this house under protective detail. Tomorrow, I want you both to come to the station. We’re going to go through the server logs together, and you’re going to tell me everything you remember about every person in that room. Someone in this neighborhood opened the basement door three times. Someone is still sending the signals. And someone left this phone on your porch to remind you that you’re not out of the game.”

She turned back to face them. “The question is: why are they so interested in you, Mr. Sandberg? What is it about your case that the algorithm can’t let go?”

Erik stared at the photograph on the phone screen. His scars. His cane. His denied benefits. The words that had followed him from the day he arrived: *These types can go either way.*

“I don’t know,” he said. “But I think I need to find out.”

After Marta left, Erik sat in the dark with the burner phone in his hand. The NeighborWatch feed was still scrolling, new posts appearing every few minutes. Anonymous accounts. Clinical language. The same hunger he had sensed from the beginning, sharpening into something focused and patient.

Liv was asleep on the couch, her breathing shallow and uneven. He pulled a blanket over her and walked to the window. The street was empty, but he knew it was not. Somewhere out there, a lens was still watching. A server was still processing. An algorithm was still learning.

And somewhere, in the dark behind one of those perfect curtained windows, a human hand was waiting to open the door again.

He looked down at the phone. A new notification had appeared. It was a private message, sent directly to the burner phone’s number. No sender. No profile.

*You were supposed to be next, Erik. You still are. But first, we need to finish what we started. The vote will come again. This time, will you be on the right side?*

He deleted the message and turned off the phone. But he did not throw it away. He placed it on the windowsill, where the cameras could see it, and he stood in the dark with his cane in his hand and his back screaming and his heart beating a slow, steady rhythm of resistance.

The morning would come. The investigation would continue. And Erik Sandberg, who had been denied by every system he had ever trusted, would find the person who had turned his neighborhood into a slaughterhouse and his life into a verdict.

Even if that person was closer than he dared to imagine.
